How To Fix DT180 - Table row is too wide for the table cluster & (> & bytes)

SAP Error Message - Details

• Message type: E = Error

• Message class: DT - Table activation (incl. indexes)

• Message number: 180

• Message text: Table row is too wide for the table cluster & (> & bytes)

What causes this issue?

The width of a row, in bytes, in a logical cluster table, without the
field width of the fields (except PAGENO) in the cluster key of the
table cluster, must be at most 15000 bytes.

System Response

The width of a row in this logical cluster is too large. The table
cannot therefore be checked or activated successfully.

How to fix this error?

Not all the fields that are currently defined can be included in the
table cluster. You will therefore have to delete some fields.

• What is the cause and solution for SAP error message DT180 - Table row is too wide for the table cluster & (> & bytes) ?

  The SAP error message DT180, which states "Table row is too wide for the table cluster & (> & bytes)," typically occurs when you are trying to insert or update a record in a database table that exceeds the maximum allowed size for a row in a table cluster. This can happen in SAP systems that use the database cluster feature to store multiple tables together for performance reasons.
  Cause:
  
  Row Size Exceeds Limit: The primary cause of this error is that the total size of the fields in the row exceeds the maximum limit allowed for a table cluster. In SAP, the maximum row size for a table cluster is generally 8,000 bytes, but this can vary based on the database and configuration.
  Data Type and Length: The data types and lengths of the fields in the table can contribute to the overall size. For example, using large VARCHAR or STRING fields can quickly increase the size of a row.
  Excessive Number of Fields: Having too many fields in a single table can also lead to this error, especially if the fields are of large data types.
  
  Solution:
  
  Review Table Structure: Check the structure of the table that is causing the error. Look for fields that have large data types or excessive lengths. Consider reducing the size of these fields if possible.
  Normalization: If the table is too wide, consider normalizing the database design. This means breaking the table into smaller, related tables to reduce the number of fields in any single table.
  Use of Data Types: Use appropriate data types for fields. For example, if a field is defined as a CHAR(255) but only needs to store short strings, consider changing it to CHAR(50) or VARCHAR(50).
  Check for Unused Fields: Remove any fields that are not being used or are redundant.
  Database Configuration: If applicable, check the database configuration settings. Some databases allow for configuration changes that can increase the maximum row size.
  SAP Notes: Check for any relevant SAP Notes or updates that may address this issue. SAP frequently releases updates that can improve performance or resolve known issues.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for guidelines on table design and limitations.
  Transaction Codes: Use transaction codes like SE11 (Data Dictionary) to analyze the table structure and SE14 (Database Utility) to manage database objects.
  Performance Considerations: Be aware that while reducing the size of a table row can resolve the error, it may also impact performance. Always test changes in a development environment before applying them to production.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with an SAP Basis or ABAP consultant who can provide more tailored assistance based on the specific context of your SAP environment.
